TOBACCO SMOKING-PIPE.

SPECIFICATION forming part of Letters Patent No. 633,292, datedSeptember 19, 1899.

Application filed July 2, 1897. Renewed May 29, 1899. Serial No.718,773. (No model.)

To air/Z7 whom it may concern:

Be it known that I, ISAAC NICHOLSON, a citizen of the United States,residing at Vallejo, in the county of Solano and State of California,have invented 'a new and useful Improvement in Tobacco Smoking-Pipes, ofwhich the following is a specification.

My invention relates especially to pipes for smoking tobacco, and hasfor its object the IO production of a device wherein the nicotine,ashes, and fine particles from the tobacco being consumed will not bedrawn into the mouth of the smoker. To attain this end, my inventionconsists, essentially, in a hollow perforated bridge or tube extendingacross the inside of the bowl of the pipe at a proper distance from thebottom to afford or provide a chamber or space under the said tube inthe bottom of the bowl, the said tube being a permanent part of the bowland forming a socket for the end of the stem of the pipe, all of whichwill more fully appear by a further description and reference to theaccompanying drawings, forming part of this specification.

z 5 In the said drawings, Figure 1 is a side view a of the bowl with thestem removed. Fig, 2 is a vertical cross-section; Fig. 3, a horizontalsection on the line 0: m. Fig. 4: illustrates a slight modification inwhich the tube forming 0 the hollow bridge is formed separately andafterward fixed in the bowl, the view being a ver tical section throughthe bowl and the bridge.

.A indicates the hollow bridge or tube extending across thetobacco-holding space of the bowl B above the bottom, so as to leave aspace I) under the tube.

A are perforations in the tube, preferably located on the under side,and A is the socket for the stem 0. In this position the chamber at thebase of thebowl forms a receptacle for the nicotine, ashes, and saliva,while the tube protects the aperture and passage in the stem andprevents the same from being choked or clogged, as the position of thepipe when in use maintains the tube and stem at a greater 5 or lessdownward inclination from the mouth of the smoker.

The tube A is either formed integrally with the bowl at the time of itsmanufacture, as in the case of clay bowls, or the tube is formedseparately and afterward inserted in the bowl through an aperture formedin one side and fixed in place, so as not to be disturbed when the stemis inserted into the tube. This modification is shown in Fig. 4 of thedrawings, where the bridge a is fixed across the bowl, so as to leave aspace 1) between the bridge and the bottom of the bowl.

Having thus described my invention, what I claim, and'desire to secureby Letters Pat- 6o ent, is-

In a tobacco smoking-pipe the combination of the bowl, the tubularbridge having a perforation or perforations in its lower side and fixedin the bowl above the bottom from one ISAAC NICHOLSON.
